crashes with A3000/040/25 running 1.3

[Miloslaw Smyk <thorgal%amiga.com.pl@localhost>]

Hello,

Yesterday I've installed 1.3 on our trusty A3000, with 3640 (040/25), 12MB
RAM, Ariadna and 128MB swap file. The kernel was custom compiled to exclude
almost everything not found on this machine. It works perfectly, but for
0.5-2h. By then everything goes down and after reboot a following entry is
present in the log:

This time it didn't even manage to dump core, but in other cases I also get
~14MB kernel core file. All crash entries in the log mention MMU fault.

Hints?

Ps. I'm going to try GENERIC soon, but somehow I don't feel it will change
anything... Am I wrong?
